摘要: 目的 评估2019—2023年济南市气象因素和大气污染物对流行性感冒(简称“流感”)病例数的短期影响,为完善流感预警和制定防控策略提供依据。 方法 收集2019年1月至2023年12月济南市大气污染物(PM2.5、PM10、SO2、NO2、O3和CO)日均质量浓度、日均气温、相对湿度和平均风速等气象数据,以及同期医疗机构报告的流感病例数据。采用分布滞后非线性模型(distributed lag non-linear model, DLNM)分析环境污染物对流感发病数的暴露反应关系和滞后效应。 结果 2019—2023年济南市共报告46 247例流感病例,日均25例。PM2.5、PM10、SO2的日均质量浓度变化对总人群流感发病风险的影响有统计学意义,每增加10 μg/m3,累积发病数分别增加1.208%、2.135%和0.383%。SO2、CO、NO2和O3在滞后当天的效应最明显,ER(95%CI)分别为0.103(0.063~0.144)、0.007(0.001~0.014)、0.018(0.004~0.033)和0.014(0.008~0.020);PM2.5和PM10在滞后10 d的效应最强,ER(95%CI)分别为0.098(0.017~0.186)和0.213(0.089~0.352)。 结论 济南市气象因素和大气污染物浓度的变化对流感病例数具有短期效应,应建立气象与污染风险预警机制。

Abstract: Objective To evaluate the short-term effects of meteorological factors and air pollutants on influenza cases in Jinan City from 2019 to 2023, and to provide evidence for improving influenza early warning and prevention strategies. Methods Daily average mass concentrations of air pollutants(PM2.5, PM10, SO2, NO2, O3, and CO), daily average temperature, relative humidity, and average wind speed in Jinan from January 2019 to December 2023, as well as influenza case data reported by medical institutions during the same period, were collected. The distributed lag non-linear model(DLNM)was used to analyze the exposure-response relationship and lag effects of environmental pollutants on influenza incidence. Results A total of 46,247 influenza cases was reported in Jinan from 2019 to 2023, with an average of 25 cases per day. The daily average mass concentration changes of PM2.5, PM10, and SO2 had statistically significant effects on the risk of influenza incidence. A 10 μg/m3 increase in PM2.5, PM10, and SO2 was associated with 1.208%, 2.135%, and 0.383% increases in cumulative influenza cases, respectively. SO2, CO, NO2, and O3 had the strongest effects on the same day, with ER(95%CI)of 0.103(0.063-0.144), 0.007(0.001-0.014), 0.018(0.004-0.033), and 0.014(0.008-0.020), respectively. The effects of PM2.5 and PM10 were strongest at lag 10 d, with ER(95%CI)of 0.098(0.017-0.186)and 0.213(0.089-0.352), respectively. Conclusion Meteorological factors and air pollutant concentrations have short-term effects on influenza cases in Jinan. A risk warning mechanism for meteorology and air pollution should be established.
